anyone managed to switch copilot off in windows 11 for good?

hiding the taskbar button doesn't stick because copilot is a normal app now, not part of the taskbar. uninstall it instead: Settings > Apps > Installed apps, search copilot, three dots > Uninstall. that's survived updates for me so far. if your keyboard has a copilot key, you can point it at something else under Settings > Personalization > Text input, there's a customize copilot key option. the old group policy "turn off windows copilot" was for the earlier version and doesn't really do anything to the new app, so don't waste time on that one.
